Deng is day to day. Already without star point guard Derrick Rose, the Bulls were missing their two best scorers, and it showed.

After 11 points in the first quarter, Boozer didn’t score again until the final two minutes.

Gibson was especially active on the offensive glass. He battled for two offensive boards and a putback on one possession three minutes into the second quarter.

Detroit went 6 for 8 from 3-point range in the first half to make up for an inability to finish inside. The Pistons failed to convert a bunch of opportunities under the rim but the game was tied at 47 at halftime.

Chicago has lost seven of its last nine games, but was coming off a 20-point win over Miami on Thursday.

NOTES: Both Gibson and Joakim Noah were whistled for technical fouls. ... Bulls coach Tom Thibodeau said Deng has been dealing with the injury since the teams met in Detroit on Nov. 27. ... Pistons guard Rodney Stuckey left in the second quarter with a sore left knee and did not return. He finished with two points in 10 minutes.
